Additional Services include injection molding and fabrication                                                                   


                              

Injection molding involves heating plastic to high temperatures sometimes in
excess of 600 degrees and forcing the liquid plastic under extreme pressure and
clamping force into a steel mold. The mold is then rapidly chilled and the part is
ejected all within seconds. Injection molding is the ultimate method for high volume
part production where complex geometry and high levels of 3D detail are required.

Materials

Depending on your requirements, literally thousands of materials can be injection molded. These range from polypropylene used for toys to ABS used in consumer electronics to nylon used for engineering grade applications to silicone used for high heat requirements. See our material selection guide to learn about some of the more common plastics.

 

         

 

Advantages to injection molding

  • parts with complex geometry are easily achieved
  • cycle times are fast making parts cost effective
  • multiple parts made in one mold meets production demands multiple cavity or family mold
  • close tolerances are easily met sometimes under .001 of an inch

Injection Mold

 

 

 

Special characteristics of injection molded parts

  • reinforced with glass or graphite – exhibits metal characteristics
  • resistant to extreme hot or cold -40 to 500F
  • resistant to caustic chemicals and UV exposure
  • low CLTE (co-efficient of linear thermal expansion) good for outdoor applications)
  • exhibits rubber like characteristics when using thermoplastic elastomers
  • anti-stat inhibitors
  • chrome plating for automotive applications
